The senatus consultum de Bacchanalibus ("senatorial decree concerning the Bacchanalia") is a notable Old Latin inscription[1] dating to 186 BC.[2] It was discovered in 1640 at Tiriolo, southern Italy. Published by the presiding praetor, it conveys the substance of a decree of the Roman Senate prohibiting the Bacchanalia throughout all Italy, except in certain special cases which must be approved specifically by the Senate.

When members of the elite began to participate, information was put before the Senate by Publius Aebutius and his lover and neighbour Hispala Faecenia, who was also a well-known prostitute, as told in the Ab Urbe Condita Libri of Livy. The cult was held to be a threat to the security of the state, investigators were appointed, rewards were offered to informants, legal processes were put in place and the Senate began the official suppression of the cult throughout Italy. According to the Augustan historian Livy, the chief historical source, many committed suicide to avoid indictment.[3] The stated penalty for leadership was death. Livy stated that there were more executions than imprisonments.[4]
After the conspiracy had been quelled the Bacchanalia survived in southern Italy.

The Senatus consultum de Bacchanalibus can be seen as an example of realpolitik, a display of the Roman senate's authority to its Italian allies after the Second Punic War, and a reminder to any Roman politician, populist and would-be generalissimo that the Senate's collective authority trumped all personal ambition.[5] Nevertheless, the extent and ferocity of the official response to the Bacchanalia was probably unprecedented, and betrays some form of moral panic on the part of Roman authorities; Burkert finds "nothing comparable in religious history before the persecutions of Christians".[6][7]

The spelling of the text of the Senatus consultum differs in many predictable ways from the spelling of Classical Latin. Some of these differences are merely orthographical; others reflect archaic pronunciations or other archaisms in the forms of words.

In Classical Latin, geminate (or long) consonants are consistently written with a sequence of two letters: e.g., cc, ll, ss for [kː], [lː], [sː]. These geminate consonants are not represented in the Senatus consultum:

EI at the end of a word often corresponds to Classical short i or to no vowel at all. However, in many cases such as sibī, utī, archaizing Classical forms ending in ī are also found, especially in poetry.

V appears for Classical Latin i in FACILVMED (27:6) facillimē, CAPVTALEM capitālem and NOMINVS nōminis. The spelling of CAPVTALEM recalls its origin from the noun caput. The ending -umus for -imus occurs frequently in archaic Classical Latin texts; the vowel represented interchangeably by u and i may have been a central vowel distinct in sound from both. Possibly OINVORSEI (19:4) ūniversī belongs here too, if one may read it as oinu(v)orsei.

The last two words AGRO TEVRANO (30:7-8) omit the final -d, despite containing the same ablative ending elsewhere written -OD; this fact suggests that at the time of writing, the final -d was no longer pronounced in ordinary speech.

Archaic gn- is found for n- at the beginning of the verb nosco

GNOSCIER (27:7) noscī.

The archaic passive infinitive ending -ier (for Classical ī) is used

FIGIER (27:3) fīgī, GNOSCIER (27:7) noscī.

QVOM (18:4) appears for Classical cum, also known in the archaic Classical form quum.

In Classical Latin the prefixes ex- and dis- become ē- and dī- before voiced consonants. In the Senatus consultum, they are still written EX and DIS:

"Quintus Marcius, the son of Lucius, and Spurius Postumius, consulted the senate on the Nones of October (7th), at the temple of the Bellonae. Marcus Claudius, son of Marcus, Lucius Valerius, son of Publius, and Quintus Minucius, son of Gaius, were the committee for drawing up the report. Regarding the Bacchanalia, it was resolved to give the following directions to those who are in alliance with us: No one of them is to possess a place where the festivals of Bacchus are celebrated; if there are any who claim that it is necessary for them to have such a place, they are to come to Rome to the praetor urbanus, and the senate is to decide on those matters, when their claims have been heard, provided that not less than 100 senators are present when the affair is discussed. No man is to be a Bacchantian, neither a Roman citizen, nor one of the Latin name, nor any of our allies unless they come to the praetor urbanus, and he in accordance with the opinion of the senate expressed when not less than 100 senators are present at the discussion, shall have given leave. Carried. No man is to be a priest; no one, either man or woman, is to be an officer (to manage the temporal affairs of the organization); nor is anyone of them to have charge of a common treasury; no one shall appoint either man or woman to be master or to act as master; henceforth they shall not form conspiracies among themselves, stir up any disorder, make mutual promises or agreements, or interchange pledges; no one shall observe the sacred rites either in public or private or outside the city, unless he comes to the praetor urbanus, and he, in accordance with the opinion of the senate, expressed when no less than 100 senators are present at the discussion, shall have given leave. Carried. No one in a company of more than five persons altogether, men and women, shall observe the sacred rites, nor in that company shall there be present more than two men or three women, unless in accordance with the opinion of the praetor urbanus and the senate as written above. See that you declare it in the assembly (contio) for not less than three market days; that you may know the opinion of the senate this was their judgment: if there are any who have acted contrary to what was written above, they have decided that a proceeding for a capital offense should be instituted against them; the senate has justly decreed that you should inscribe this on a brazen tablet, and that you should order it to be placed where it can be easiest read; see to it that the revelries of Bacchus, if there be any, except in case there be concerned in the matter something sacred, as was written above, be disbanded within ten days after this letter shall be delivered to you. In the Teuranian field."
